SASH-LOCK.

No. 887,321. Specification of Letters Patent. Patented May 12, 1908. Application filed April 10, 1907. Serial No. 367,430. To all whom it may concern: elongated slot 11 in a depressed portion 12.

Be it known that I, FLOREAN I. FisoHER, a These three slots 8, 10 and 11, are located in subject of the Crown of Roumania, and resialinement with each other. A sliding block dent of the borough of Manhattan, in the 13 is located between the shank 6 of the city and State of New York, have invented a locking bolt and the depressed portion 9 of new and useful Improvement in Sash-Locks, the face plate 1 of the casing, which block is of which the following is a specification. provided with rearwardly and forwardly eX- The object of this invention is to provide tended shanks 14, 15, the shank 14 extending a mechanically operated lock which is parthrough the slot 10 in the locking bolt shank 6 and the slot 11 in the back of the casing, and the shank 15 extending through the slot 8 in the face plate of the casing.

The shank 14 is provided with a head 16 located in the depressed portion 12 at the back of the casing and the shank 15 is provided with a head 17 located in the depressed portion 9 of the face plate of the casing. This head 17 also serves as a thumb piece for use in sliding the block 13 for controlling the movement of the head 5 of the locking bolt.

\V hen the block 13 is moved upwardly, it will permit the spring actuated shank of the locking bolt to swing the head of the locking bolt out through the hole 4 in the face plate into its locking position. hen the block 13 is moved downwardly, it will force the shank 6 and thereby the head 5 ofthe locking bolt inwardly thus withdrawing the head from its locking position. The elongated slot 8 in the 5 face plate is gradually contracted from its bottom to its top so as to insure the retention of the bolt controlling device in its raised position until positively operated upon.

For the purpose of holding the part which carries the lock to the part locked and. released by the locking bolt, I provide a swinging latch 18 having a head 19 arranged to enter a slot 20 in a plate 21 carried by the part to be locked and released. This latch is pivoted at 22 within the casing and is provided with two flat surfaces 23, 24, arranged to engage the bottom wall of the body of the casing alternately to lock the latch yieldingly in its thrown and withdrawn positions. This latch may be provided with projections 25, 26, on its head 19 for use in manually swinging the latch into and out of operative position.

A stop 27 is provided within the body portion of the casing for limiting the inward movement of the latch.

with looking and releasing window sashes.

A practical embodiment of this invention is represented in the accompanying drawings, in which nal central section with the parts in the osition which they assume when the be t is thrown into its locking position, Fig. 2 is a similar view with the parts in the position drawn from its locking position, Fig. 3 is a rear elevation of the lock, Fig. 4 is a front elevation of the lock, Fig. 5 is a perspective view of the spring actuated locking bolt,

operated slide for controlling the movements of the locking bolt, and Fig. 7 is a horizontal section taken in the plane of the line AA of Fig. 1 looking in. the direction of the arrows.

and a box portion 2 which is secured around its edges to the back of the face plate preferably by roviding the box portion with prongs 3 a ong its edges which are riveted in The face plate 1 is provided with a bolt hole 4 through which the head 5 of the locking bolt is moved into and out of its locking position. This locking bolt is provided which is secured at 7 to the back of the body portion 2 of the casing. This locking bolt normally occupies its locking position with the head 5 projecting through the hole 4 in spring shank 6.

The device which I have shown for manually controlling the movements of the locking bolt is constructed and arranged as folhole 4 with a vertically e ongated slot 8 located in a depressed portion 9 in the face What I claim 1s:

plate. The shank 6 of the locking bolt is 1. A lock comprising a casing, a locking also provided with a vertically elongaged bolt havinga spring shank normally holding 55 slot 10 and the back wall of the bodyportion the bolt in its locking position and a sliding 2 of the casing is provided with a vertically block interposed between the casing and the spring shank arranged to withdraw the bolt sliding in the rear and front walls of the when the block is moved toward the free end casing.

of the bolt and to permit the bolt to return to its locking position when the block is moved away from the free end of the bolt.

2. A look comprising a casing, a bolt having a spring shank normally holding the bolt in its looking position, and a sliding block engaging the shank for controlling the movements of the bolt, said bloc k having rearwardly and forwardly extended shanks In testimony, as my invention, presence of two witnesses,

that I claim the foregoing I have signed my name in this third day of locking April, 1907.
